The fine spell of hot weather in July 2013 has meant that we can ‘crack on’ with getting the barn erected. Previous posts are here<\/p>\n

Part 1<\/a>
\nPart 2<\/a>
\nPart 3<\/a><\/p>\n

At the end of part 3 John and Jonathan were leaning smugly against the frame having assembled it. After Jonathan went back home to Spain, I (John) carried on fixing the 75mm x 50mm purlins across the rafters. These are necessary to support and fix the roofing sheets. I decided to use simple corrugated steel sheets for the roof. These are not too expensive or too heavy and are easily fixed. As the shed is partly open condensation should not be too much of a problem in winter. The sheets can be bought as plain galvanised or painted or plastic coated with the price and durability increasing accordingly. I went for the latter (most expensive and most durable) in a slate grey colour.<\/p>\n

\"John
Here you can see the purlins that John is resting the ladder on. They are nailed to the rafters and also have galvanised straps at places for ‘a belt and braces’ approach to gusting wind!<\/figcaption><\/figure>\n

Each sheet of corrugated steel is 1m wide when lapped with its neighbour and they can be bought in any length to cover the exact span (remembering to leave enough overhang for the gutter). In my case I am overlapping them a tad more to save cutting the last sheet. It is of course essential that the first sheet is positioned correctly or they will all start ‘running out’ of alignment.<\/p>\n

\"shed2\"<\/a>
John marks where to fix the sheets by hooking a line over the last fixing and along the centre of the purlin.<\/figcaption><\/figure>\n

The position of the fixings can then be marked. The Tek screw fixing are self cutting but I found it easier to either drill a pilot hole or just bang a small nail through.<\/p>\n

\"John
The sheets are fixed through the top of the corrugation, not the valley, to prevent leaks. The screws are self tapping but I found it easier to make a starter hole with a nail.<\/figcaption><\/figure>\n

If you don’t carefully mark the line of the purlin you risk having a hole in your roof and nothing underneath to screw into!<\/p>\n

\"The
The Tek screw has a rubber collar to prevent water ingress.<\/figcaption><\/figure>\n

The screws should be tightened down until they are holding firmly but not crushing the corrugation. They can be capped of with plastic caps (a dab of silicone under the cap before putting them on is not a bad idea to stop them coming loose).<\/p>\n

\"It
It is screwed into the purlin with an 8mm nut driver on an electric drill<\/figcaption><\/figure>\n
\"Here
Here you can see the fixed roof with another sheet waiting to be fixed as I work my way across the roof.<\/figcaption><\/figure>\n

So the roof will soon be finished and then I only have to fix the side cladding boards and do a bit of tidying up etc which I hope to show in the last part.<\/p>\n
